Local Codex runtime
TextOS gives Codex-style work a Linux environment on your Android device: files, shell commands, generated pages, and repairable runtime state.
TextOS by Lightray
A local Android Linux runtime for Codex work.
Use your ChatGPT/Codex sign-in. TextOS does not require a separate OpenAI API key or API billing setup; OpenAI plan limits and credits still apply.
Inside TextOS
TextOS gives Codex-style work a Linux environment on your Android device: files, shell commands, generated pages, and repairable runtime state.
Sign in through the Codex/ChatGPT flow. TextOS is not asking you to bring an API key or manage separate pay-per-token API billing inside the app.
Projects and runtime files live on device by default. Prompts and selected context leave the device when you intentionally use AI features.
TextOS is not an official OpenAI app. Codex and ChatGPT access, availability, usage limits, and credits are governed by your OpenAI account and plan.
